Rating: (see review/s)

"Received as a complete package with instructions easy to follow. Was able to remove old system and install the new system within about 1 hr. Used the clamp that was sent and did not weld pipes, just incase I wanted to remove easily. The system has a nice tone outside, however, it is quite loud in the cab of the truck. Had to turn the radio a few clicks just to hear the music. Just a note, this system has not increased power or increase gas mileage." posted by: Old Car Guy on October 14, 2009
